Shipmates: I am about to start on an ENGEL GATO build, and need some tips / tricks / tools / advice / magic / witchcraft for cutting / drilling the thousands of holes on this hull. Any and all advice is welcome. Any build advice specific to this sub kit is welcome also. Thank you in advance.

A technique that I have helpful when making any sort of opening in a fiberglass hull is to cover the general area to be cut with tape (clear or blue masking, etc.). This will prevent most of the edge chipping that occurs.

I also draw all the openings on the hull, assuming that there aren't pre-scribed lines, to act as guidance while cutting. I cover those markings with clear tape which prevents the lines from getting erased as you work on the piece. If I use an opaque tape, I draw the guides directly on the tape.
